Content.Load<>("path")

i find a problem
when i need to use content.load<>(“path”) to load my texture, if the path is like ./a/a, i dont know what i should write to replace “path”
if i write
content.load("./a/a")(without blank)
, it will say"System.NullReferenceException:“Object reference not set to an instance of an object.”"
if i write
content.load("./ a/ a")(with blank)
, it will say"Microsoft.Xna.Framework.Content.ContentLoadException:“The content file was not found.”"
what right way to write path

Try specifying a decreasing slash \ instead of /.

ok, i found i make a mistake
i use
list.add
to try to add textures, this cause error, but i dont know what

List player;
…
player.Add(content.Load(".\player\player2"));//error ,path is ok if player is Texture2D[]

5

i see the programme, it say \ is replaced to /, maybe the problem is not path
i have solve the problem by rewrite there.

this is the problem code example, replace Texture[] to List<> and initial can solve bug

using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Graphics;
using Microsoft.Xna.Framework.Input;
using System.Collections.Generic;

namespace MyGame;

public class Game1 : Game
{
private GraphicsDeviceManager _graphics;
private SpriteBatch _spriteBatch;
//public List role = new List();
public Texture2D[] role;

public Game1()
{
    _graphics = new GraphicsDeviceManager(this);
    Content.RootDirectory = "Content";
    IsMouseVisible = true;
}

protected override void Initialize()
{
    // TODO: Add your initialization logic here

    base.Initialize();
}

protected override async void LoadContent()
{
    _spriteBatch = new SpriteBatch(GraphicsDevice);

    //role.Add(Content.Load<Texture2D>("player1"));
    //role.Add(Content.Load<Texture2D>("player2"));
    //role.Add(Content.Load<Texture2D>("player3"));
    role[0] = Content.Load<Texture2D>("player1");
    role[1] = Content.Load<Texture2D>("player2");

//error System.NullReferenceException:“Object reference not set to an instance of an object.”
role[2] = Content.Load(“player3”);
// TODO: use this.Content to load your game content here
}

protected override void Update(GameTime gameTime)
{
    if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed || Keyboard.GetState().IsKeyDown(Keys.Escape))
        Exit();

    // TODO: Add your update logic here

    base.Update(gameTime);
}

protected override void Draw(GameTime gameTime)
{
    GraphicsDevice.Clear(Color.CornflowerBlue);

    // TODO: Add your drawing code here

    base.Draw(gameTime);
}

}

You have not initialised role.
you need to do:

List<Texture2D> role = new List<Texture2D>();

Then this should work:

role.Add(Content.Load<Texture2D>("player1"));

(When you get the error, it is role that is not set to an instance of an object)
